摘要: Adjusting the spacers between electron-acceptor and elector-donor is important to design organic ternary memory material but rarely reported. In this paper, two small molecules, ZIPGA ZIPCAD with benzene ring or triphenylamine as spacers, were designed synthesized fabricate devices. The Al/ZIPGA/indium-tin oxide (ITO) device showed characteristics, whereas Al/ZIPCAD/ITO had no obvious characteristics. Density functional theory calculation, X-ray diffraction (XRD) atomic force microscopy (AFM) employed interpret different properties. thin film has closer intermolecular packing flatter surface morphology than film, which was favorable electron migration. This work demonstrates importance of reveals that may be not a good spacer in new material.
